본 발명은, 재생 전용 블루레이 디스크(BD-ROM: Blu-ray Disc-ROM)와 같은 고밀도 광디스크가 불법 복제된 광디스크인 지를 판별할 수 있도록 하기 위한 고밀도 광디스크와, 그에 따른 불법 복제 판별방법에 관한 것이다. The present invention, the reproduction-only Blu-ray disc (BD-ROM: Blu-ray Disc-ROM) and the high density optical disk is the high density optical disk such as to allow to determine if pirated optical disk of, on the counterfeit discrimination method accordingly will be.

최근에는, 고화질의 비디오 데이터와 고음질의 오디오 데이터를 장시간 동안 기록 저장할 수 있는 새로운 고밀도 광디스크, 예를 들어 재기록 가능한 블루레이 디스크(BD-RE: Blu-ray Disc-Rewritable)에 대한 규격화 작업이 급속히 진전됨에 따라, 관련 제품이 개발 출시되어 상용화될 것으로 기대되고 있다. Recently, a new high density optical disc that can store the recording for a long period of time the quality video and audio data of high quality, for example, a rewritable Blu-ray disc (BD-RE: Blu-ray Disc-Rewritable) standardization is rapidly advanced to the , it is expected to be related to the commercialization of products developed is released as.

한편, 상기 BD-RE는, 도 1에 도시한 바와 같이, 디스크의 내주면에 클램핑 영역과, 트랜지션 영역 및 BCA(Burst Cutting Area) 영역, 그리고 리드인 영역(Lead-In Area)이 차례대로 존재하며, 디스크의 중심과 외주에는, 데이터 영역(Data Area)과 리드아웃 영역(Lead-Out Area)이 각각 존재하는 디스크 구조를 갖는다. On the other hand, as the BD-RE is shown in Figure 1, is present in the clamping area to the inner circumferential surface of the disk, a transition region and a BCA (Burst Cutting Area) area, and an area (Lead-In Area) leads in turn , in the center and the periphery of the disk, the data area (data area) and a lead-out area (lead-out area) to have a disc structure present, respectively.

또한, 상기 리드인 영역에는, 제1 가아드(Guard 1) 영역과 PIC(Permanent Information & Control data) 영역, 그리고 제2 가아드(Guard 2) 영역과 정보 2(Info 2) 영역 및 OPC(Optimum Power Control) 영역 등이 구분 할당되어 있는 데, 상기 제1 가아드 영역과 PIC 영역은, 사전에 데이터가 미리 기록되어 있는 영역(Pre-recorded area)인 반면, 그 나머지 리드인 영역과, 상기 데이터 영역, 그리고 상기 리드아웃 영역은, 새로운 데이터가 재 기록되는 영역(Rewritable area)이다. Further, the lead-in area, the first ego de (Guard 1) area and a PIC (Permanent Information & Control data) area, and the second ego de (Guard 2) area, and the information 2 (Info 2) area, and the OPC (Optimum Power Control) area, such as two minutes to which are assigned said first ego de area and PIC area, while the pre-area in which data is recorded in advance (pre-recorded area), the remaining lead-in area and the data area, and the lead-out area is an area (Rewritable area) that the new data are re-recorded.

그리고, 상기 PIC 영역에는, 영구적으로 보존되어야 할 디스크의 주요 일반 정보들이 기록 저장되는 영역으로서, 고주파 변조(HFM: High Frequency Modulated) 그루브가 형성 기록되는 데, 상기 HFM 그루브는, 도 2에 도시한 바와 같이, 바이-페이즈 변조(Bi-Phase Modulated) 방식에 의해 변조 기록되어 디스크 정보(DI: Disc Information)를 기록 저장하게 된다. Then, in the PIC zone, as an area which is the main general information is the record of the disc is to be preserved permanently, the high frequency modulation (HFM: High Frequency Modulated) to which grooves are formed in the recording, the HFM groove, shown in Fig. 2 , by as-modulated recording by phase modulation (bi-phase modulated) disk method information: it is storing (DI disc information) recording.

한편, 상기 BD-RE의 개발과 더불어, 현재 관련업체들간에 논의되고 있는 새로운 고밀도 광디스크, 예를 들어 재생 전용 블루레이 디스크(BD-ROM)의 경우, 도 3에 도시한 바와 같이, 이너(Inner) 영역, 클램핑(Clamping) 영역, 트랜지션(Transition) 영역, 그리고 정보(Information) 영역과 림(Rim) 영역을 갖되, 데이터 영역(Data Zone)에 기록되는 A/V 스트림의 메인 데이터는, 불법 복사를 방지하기 위한 복사 방지 정보(CPI: Copy Protection Information)에 의해 엔크립션(Encryption)되어 암호화 데이터로 기록될 수 있다. On the other hand, in the case of addition to the development of the BD-RE, a new high density optical disc that is being discussed in between the current-related areas, for example, reproduction-only Blu-ray disc (BD-ROM), 3, the inner (Inner ) region, a clamping (clamping) zone, a transition (transition) region, and the information (information) area and the rim (rim) and has a region, the main data of a / V streams recorded on the data area (data zone), the illegal copy copy protection information to prevent the yen by (CPI copy Protection information) is the creep Sean (encryption) can be recorded as encrypted data.

그리고, 상기 정보 영역 내에 구분 할당되는 PIC 영역에는, 상기 복사 방지 정보(CPI)와 디스크 정보(DI)가 포함 기록되며, 광디스크 장치에서는, 초기 서보 동작 수행시, 상기 PIC 영역에 기록된 복사 방지 정보(CPI)를 검출한 후, 그 복사 방지 정보를 이용하여, 상기 데이터 영역에 암호화 기록된 메인 데이터를, 디크립션(Decryption)하여, 비 암호화 데이터로 재생 출력하게 된다. And, in the PIC zone, it separated assigned in the information area, and the copy protection information (CPI) and disc information (DI) includes recording, the optical disc apparatus, the copy protection information recorded at the time of performing initial servo operation, the PIC area after detecting (CPI), by using the copy protection information, and the encrypted main data recorded in the data area, decryption (decryption), is reproduced and output to a non-encrypted data.

그러나, 광디스크 장치에 의해 디크립션되어 재생 출력되는 BD-ROM의 데이터 스트림을, 개인용 컴퓨터의 하드 디스크(HDD)와 같은 스토리지에 불법적으로 기록 저장한 후, BD-ROM 포맷터(Formatter)를 이용하여, 복사 방지 정보(CPI) 없이, 포맷팅한 다음, 마스터링 머신(Mastering Machine)을 이용하여 불법적으로 BD-ROM을 제작하는 경우, 상기 불법 제작된 BD-ROM에는, 복사 방지 정보가 없으면서, 비 암호화된 데이터 스트림이 기록되기 때문에, 합법적인 프로세스를 거쳐, 복사 방지 정보가 없으면서, 비 암호화된 데이터 스트림이 기록되어 있는 BD-ROM과 동일하게 되므로, 불법 복제 여부를 판별할 수 없게 되는 데, 이를 해결할 수 있는 효율적인 방안이 아직 마련되어 있지 않은 실정이다. However, after the data stream of the BD-ROM that is illustration decryption by the optical disc device is reproduced and output, illegal recording stored in a storage such as a hard disk (HDD) of a personal computer, by using the BD-ROM formatter (Formatter) without, copy protection information (CPI), the formatting, and then, when fabricating the BD-ROM is illegally using a mastering machine (mastering machine), is the illegal manufacturing a BD-ROM, eopeumyeonseo the copy protection information, unencrypted since the data stream is recorded through the legal process, eopeumyeonseo copy protection information, because the non-encrypted data stream is the same as the BD-ROM that has been recorded, you are unable to determine the pirated or not, fix it effective ways to the actual circumstances is not yet available.

따라서, 본 발명은 상기와 같은 실정을 감안하여 창작된 것으로서, 재생 전용 블루레이 디스크(BD-ROM)와 같은 고밀도 광디스크가 불법적인 프로세스를 거쳐 제작된 광디스크인지 또는 합법적인 프로세스를 거쳐 제작된 광디스크인지를 정확하게 판별할 수 있도록 함과 아울러, 그 판별 결과에 대응되는 재생 제어동작이 수행될 수 있도록 하기 위한 고밀도 광디스크와, 그에 따라 불법 복제 판별방법을 제공하는 데, 그 목적이 있는 것이다. Accordingly, the present invention is that the as the original in view of the circumstances as described above, the reproduction-only Blu-ray disc (BD-ROM) and the high-density optical disc is an optical disc or an optical disc manufactured after the legitimate process produced through the illegal process such to ensure that they accurately determined also and at the same time, and the high density optical disk for allowing the reproduction control operation corresponding to the judgment result can be performed, to provide a counterfeit discrimination method accordingly, it will have the purpose.

이하, 본 발명에 따른 고밀도 광디스크와, 그에 따른 불법 복제 판별방법에 대한 바람직한 실시예에 대해, 첨부된 도면을 참조하여 상세히 설명한다. Hereinafter, for the preferred embodiment for the high density optical disk and, therefore counterfeit discrimination method according according to the invention, with reference to the accompanying drawings will be described in detail.

우선, 본 발명에 따른 고밀도 광디스크, 예를 들어 재생 전용 블루레이 디스크(BD-ROM)는, 도 3을 참조로 전술한 바와 같이, 이너 영역, 클램핑 영역, 트랜지 션 영역, 그리고 정보 영역과 림 영역의 디스크 구조를 갖으며, 상기 정보 영역 내에 구분 할당되는 PIC 영역에는, 도 4에 도시한 바와 같이, 디스크 일반 주요정보인 디스크 정보(DI)가 포함 기록됨과 아울러, 데이터 영역(Data Zone)에 암호화 기록된 A/V 스트림의 메인 데이터를 비 암호화 데이터로 디크립션(Decryption)하기 위한 키 값인 복사 방지 정보(CPI)가 포함 기록된다. First of all, the high density optical disk, for example, a reproduction-only Blu-ray disc (BD-ROM), as described above for Figure 3 as a reference, an inner area, clamping area, Transitional design area, and the information area and the rim the was has a disc structure of the region, as shown distinction is PIC area allocated, 4 in the information area, the disc general main information of the disc information (DI) contains written and, at the same time, the data area (data zone) the main data recorded in the encrypted a / V stream in a non-encrypted data, decryption (decryption) Start key value for preventing information (CPI) is recorded it included.

그리고, 상기 데이터 영역에 암호화되지 않은 A/V 스트림의 메인 데이터가 기록되는 경우, 상기 PIC 영역에는, 복사 방지 정보(CPI)가 별도로 기록되지 않는 데, 상기와 같이 PIC 영역에 선택적으로 기록되거나, 또는 미 기록될 수 있는 복사 방지 정보의 기록 여부를 나타내기 위한 식별정보, 예를 들어 1 바이트의 기록크기를 갖는 복사 방지 정보 플래그(CPI_Flag)를, 상기 복사 방지 정보 내에 포함 기록하거나, 또는 PIC 영역 내에 별도로 구분 기록하게 된다. And, when the main data of A / V stream is not encrypted in the data area is recorded, in the PIC zone, to the copy protection information (CPI) are not recorded separately, or optionally written to the PIC zone as described above, or identification for indicating the recording whether the non-copy-protected information that can be written information, for example, including recording the copy having a recording size of one byte protection information flag (CPI_Flag), in the copy protection information, or PIC area It is additionally recorded in the nine minutes.

이에 따라, 합법적인 프로세스를 거쳐 제작된 BD-ROM의 PIC 영역에는, CPI 정보가 기록됨과 아울러, CPI_Flag가 복사 방지 정보의 기록을 나타내는 값, 예를 들어 'CPI_Flag=1'이 기록되거나, 또는 CPI 정보가 미 기록됨과 아울러, CPI_Flag가 복사 방지 정보의 미 기록을 나타내는 값, 예를 들어 'CPI_Flag=0'이 기록된다. Accordingly, in the PIC area of ​​the BD-ROM production through legitimate processes, and CPI information is recorded as well, the value CPI_Flag indicating the recording of the copy protection information, for example, or the 'CPI_Flag = 1' record, or CPI information as well as the non-recorded, CPI_Flag value indicating the non-recording of the copy protection information, for example the 'CPI_Flag = 0' is written.

따라서, 도 5에 도시한 바와 같이, 합법적인 BD-ROM 제작 프로세스를 거쳐 CPI 정보와 'CPI_Flag=1'이 기록된 BD-ROM(10), 또는 CPI 정보가 미 기록됨과 아울러, 'CPI_Flag=0'이 기록된 BD-ROM(11)을, BD-ROM 레코더 또는 플레이어 등과 같은 광디스크 장치(100)에서 재생한 후, 그 BD-ROM의 데이터 스트림을, 개인용 컴퓨터의 하드 디스크(HDD)와 같은 스토리지(200)에 불법적으로 기록 저장한 다음, BD- ROM 포맷터(Formatter)(300)를 이용하여, 복사 방지 정보(CPI) 없이, 포맷팅한 한 후, 마스터링 머신(400)을 이용하여 불법적으로 BD-ROM(20)을 제작하게 되면, 상기 불법적으로 제작된 BD-ROM(20)에는, CPI_Flag가 '1'로 기록되지만, CPI 정보는 기록되지 않게 된다. Thus, as shown in Fig. 5, a legitimate BD-ROM through the production process of this CPI information and 'CPI_Flag = 1' recorded BD-ROM (10), or CPI information as well as the non-recorded, 'CPI_Flag = 0 the BD-ROM (11) is "recorded, BD-ROM recorder, or after playback from the optical disc apparatus 100 such as a player, the storage of a data stream of the BD-ROM, and a hard disk (HDD) of a personal computer the illegal record stored in 200 and then, BD- ROM formatter (formatter) illegally BD by using the no copy protection information (CPI), formatting a one then the mastering machine 400 using a 300 When the -ROM (20) the production, in a BD-ROM (20) prepared by the above illegal, but CPI_Flag is recorded as '1', CPI information is not recorded.

즉, 도 6에 도시한 바와 같이, 복사 방지 컨트롤 칩(CPCC: Copy Protection Control Chip)과 포맷터(Formatter)로 구성된 BD-ROM 포맷터(300)에, 콘텐츠 프로바이더 파일(Content Provider File)에서 제공되는 컨트롤 데이터와 메인 데이터를 인가하여, BD-ROM을 포맷팅한 후, 마스터링 머신(400)을 이용하여, BD-ROM을 합법적으로 제작하게 되면, CPI 정보와 'CPI_Flag=1'이 기록된 BD-ROM이 제작되거나, 또는 CPI 정보가 기록되어 있지 않으면서 'CPI_Flag=0'이 기록된 BD-ROM이 정상적으로 제작된다. That is, as shown in Figure 6, the copy protection control chip: provided by (CPCC Copy Protection Control Chip) and a formatter configured to (Formatter) BD-ROM formatter 300, a content provider file (Content Provider File) to the control data and the main data is applied, and then formatting the BD-ROM, by using a mastering machine 400, when the BD-ROM produced legally, CPI information and 'CPI_Flag = 1' the recording BD- ROM is produced, or CPI, or if the information is produced books 'CPI_Flag = 0' is recorded BD-ROM is not properly recorded.

그러나, 도 5를 참조로 전술한 바와 같이, 불법적인 프로세스를 거쳐 BD-ROM을 제작하게 되면, CPI 정보가 정상적으로 기록되어 있지 않으면서도 CPI 정보가 기록되어 있음을 나타내는 'CPI_Flag=1'이 기록된 BD-ROM이 불법적으로 제작되므로, 광디스크 장치에서는, 상기와 같이 불법 제작된 BD-ROM(No CPI & CPI_Flag=1)을 용이하게 구분 판별할 수 있게 된다. However, as described above for FIG. 5 as a reference, the When making the BD-ROM through the illegal process, CPI information is not normally recorded to indicate that the even CPI information is recorded if the 'CPI_Flag = 1' is recorded since a BD-ROM is made of illegal optical disc in the apparatus, it is possible to determine the illegal manufacturing BD-ROM easily separated (No CPI & CPI_Flag = 1) as described above.

한편, 도 7은 본 발명에 따른 불법 복제 판별방법이 적용되는 광디스크 장치에 대한 일부 구성을 도시한 것으로, 상기 광디스크 장치에는, 롬 마크 디코더부(50), 키 디크립션 및 디코딩부(51), 메인 데이터 디크립션부(52), 메인 데이터 디코더부(53) 등이 하드웨어 또는 소프트웨어 구성으로 포함될 수 있는 데, 상기 롬 마크 디코더부(50)에서는, BD-ROM의 PIC 영역에 기록된 CPI 정보와 CPI_Flag를 디코딩하게 되고, 상기 키 디크립션 및 디코딩부(51)에서는, 상기 CPI 정보를 암호화 해독을 위한 디크립션 키(Decryption Key) 값으로 디크립션 및 디코딩하여, 상기 메인 데이터 디크립션부(52)로 출력하게 된다. On the other hand, Figure 7 that shows a part of the configuration of an optical disk apparatus to which the determination piracy method according to the present invention is applied, in the optical disc apparatus, ROM mark decoder unit 50, a key decryption and the decoding section 51 , in the main data decryptor syeonbu 52, to which like the main data decoder 53 may be included in hardware or software configuration, the ROM mark decoder unit 50, the CPI information recorded in the PIC area of ​​the BD-ROM and is decoded to CPI_Flag, the key decryption and the decoding portion (51), the by decryption and decoding to the decryption key (decryption key) value for encrypting the CPI information, the main data decryptor is output to the syeonbu 52.

또한, 상기 메인 디크립션부(52)에서는, 상기 디크립션 키 값을 이용하여, 암호화된 메인 데이터 스트림을 디크립션하게 되고, 상기 메인 데이터 디코더부(53)에서는, 상기 디크립션된 메인 데이터 스트림을 원래의 데이터로 복원하여 재생 출력하는 일련의 동작을 수행하게 되는 데, 상기 롬 마크 디코더부(50)에서는, 전술한 바와 같이, BD-ROM의 PIC 영역에, CPI 정보가 정상적으로 기록되어 있지 않으면서, CPI_Flag가 '1'로 기록되어 있는 경우, 상기 BD-ROM이 불법적인 프로세스를 거쳐 제작된 BD-ROM이라고 판별한 후, 재생 중지 컨트롤(Playback Stop Control) 신호를, 상기 메인 데이터 디크립션부(52)로 출력하여, 데이터 재생 동작을 강제적으로 중지시키게 된다. Further, in the main decryption syeonbu 52, using the decryption key value, the encrypted main data stream and the illustration decryptor, in the main data, the decoder unit 53, the main design the decryptor the data stream in the PIC area of ​​the to be carried out a series of operations for the reproduction output to restore the original data, the ROM mark decoder unit 50, as described above, BD-ROM, the CPI information is normally recorded not do standing, CPI_Flag the case that has been recorded to "1", the BD-ROM is illegal and then determination process is referred to as the BD-ROM production via, reproduction stop control (playback stop control) signal, the main data D output to creep syeonbu 52, thereby forcibly stop the data reproduction operation.

한편, 본 발명의 다른 실시예에 따른 BD-ROM은, 도 8에 도시한 바와 같이, 리드인 영역 내의 PIC 영역에 디스크 정보(DI)와 CPI 정보, 그리고 CPI_Flag가 기록됨과 아울러, 복수의 콘텐츠 사양 정보(CSI: Contents Specific Information)가 추가 기록되는 데, 예를 들어 제1 콘텐츠 사양 정보(CSI 1)는, 일반적인 스트레이트 피트 타입(Straight Pit Type)으로 기록되고, 제2 콘텐츠 사양 정보(CSI 2)는, 워블 피트 타입(Wobbled Pit Type)으로, 각각 서로 다른 포맷으로 구분 기록되며, 상기 제1 및 제2 콘텐츠 사양 정보 중 어느 하나는, 상기 PIC 영역 이외의 다른 영 역에 기록될 수 있다. On the other hand, BD-ROM according to another embodiment of the present invention, the disc information (DI) in the PIC area within a lead-in area as shown in Figure 8 and CPI information, and the CPI_Flag is logged as well, a plurality of content specification information (CSI: contents Specific information) is to be additionally recorded, such as first content specification information (CSI 1) has been recorded in the normal straight pit type (straight pit type), the second content specification information (CSI 2) It is, as a wobble pit type (type Wobbled pit), are recorded, each separated in different formats, wherein said one of the first and second content specification information may be recorded in another area other than the PIC area.

이에 따라, 합법적인 프로세스를 거쳐 제작된 BD-ROM의 PIC 영역에는, CPI 정보와 CPI_Flag가 기록됨과 아울러, 서로 다른 포맷의 제1 및 제2 콘텐츠 사양 정보(CSI 1,2)가 각각 서로 다른 포맷으로 기록되므로, 도 5를 참조로 전술한 바와 같이, 불법적인 프로세스를 거쳐 제작된 BD-ROM(20)의 경우, CPI 정보가 정상적으로 기록되어 있지 않으면서도, CPI_Flag가 '1'로 기록됨은 물론, 상기 워블 피트 타입의 제2 콘텐츠 사양 정보(CSI 2)가, 미 기록되거나, 또는 비정상적으로 기록되므로, 상기 스트레이트 피트 타입의 제1 콘텐츠 사양 정보(CSI 1)와는 일치하지 않는 제2 콘텐츠 사양 정보가 검출된다. Accordingly, in the PIC area of ​​the BD-ROM through production of a legitimate process, CPI information and CPI_Flag is recorded and at the same time, first and second content specification information (CSI 1,2) are respectively different formats of different formats as recording because, above to Figure 5 as a reference, in the case of a BD-ROM (20) made through an illegal process, CPI information is, of course if it is not normally recorded even, CPI_Flag is written to "1", wherein the wobble pit type of the second content specification information (CSI 2), non-recorded or, or because abnormally recorded in the straight pit type of primary content specification information (CSI 1) than that does not match the second content specification information is It is detected.

즉, 도 9에 도시한 바와 같이, 복사 방지 컨트롤 칩(CPCC)과 포맷터(Formatter)로 구성된 BD-ROM 포맷터(300)에, 합법적으로 복사 방지 컨트롤 데이터와 메인 데이터를 인가하여, BD-ROM을 제작하게 되면, CPI 정보와 'CPI_Flag=1', 그리고 서로 다른 포맷으로 기록되는 제1 및 제2 콘텐츠 사양 정보(CSI 1,2)가 기록된 BD-ROM이 제작되거나, 또는 CPI 정보가 기록되지 않은 상태에서 'CPI_Flag=0'과 서로 다른 포맷으로 기록되는 제1 및 제2 콘텐츠 사양 정보(CSI 1,2)가 기록된 BD-ROM이 제작된다. That is, by applying the like, BD-ROM formatter 300, a legal copy protection control data and the main data, consisting of the copy protection control chip (CPCC) and formatter (Formatter) shown in Figure 9, the BD-ROM Once produced, CPI information and 'CPI_Flag = 1', and each of the first and second content specification information (CSI 1,2) to be recorded is recorded in a different format or BD-ROM is manufactured, or CPI information is not recorded in that the state 'CPI_Flag = 0' and each of the first and second content specification information (CSI 1,2) to be recorded in different formats recorded BD-ROM is manufactured.

그러나, 전술한 바와 같이, 불법적인 프로세스를 거쳐 BD-ROM을 제작하게 되면, CPI 정보가 정상적으로 기록되어 있지 않으면서도 'CPI_Flag=1'이 기록됨과 아울러, 상기 스트레이트 피트 타입의 제1 콘텐츠 사양 정보(CSI 1)는 정상 기록되되, 상기 워블 피트 타입의 제2 콘텐츠 사양 정보(CSI 2)가 비정상적으로 기록되거 나, 또는 미 기록되므로, 광디스크 장치에서, 상기와 같이 불법 제작된 BD-ROM을, 제1 콘텐츠 사양 정보와 제2 콘텐츠 사양 정보의 일치 여부에 근거하여, 용이하게 구분 판별할 수 있게 된다. However, when the making a BD-ROM via the illegal process, CPI information does not recorded correctly even 'CPI_Flag = 1' is written and, at the same time, the first content specification information of the straight pit type, as described above ( CSI 1) is doedoe normal recording, the wobble pit type of the second content specification information (CSI 2) has shed some light abnormally recorded in I, or a non-recording because, in the optical disc apparatus, the illegal manufacturing a BD-ROM as described above, the , it is possible to easily determine separate them based on a match of the 1 st content specification information and the second content specification information.
